Signs and Symptoms

What are the Signs and Symptoms of Concussion?

Most people with a concussion have a good recovery from symptoms experienced at the time of the injury. But for some people, symptoms can last for days, weeks, or longer. In general, recovery may be slower among older adults, young children, and teens. Those who have had a concussion in the past are also at risk of having another one and may find that it takes longer to recover if they have another concussion.

Symptoms of concussion usually fall into four categories:

Thinking/ Remembering

Physical

Emotional/ Mood

Sleep

Difficulty thinking clearly

Headache

Fuzzy or blurry vision

Irritability

Sleeping more than usual

Feeling slowed down

Nausea or vomiting
(early on)Dizziness

Sadness

Sleep less than usual

Difficulty concentrating

Sensitivity to noise or light

Balance problems

More emotional

Trouble falling asleep

Difficulty remembering new information

Feeling tired, having no energy

Nervousness or anxiety

Some of these symptoms may appear right away, while others may not be noticed for days or months after the injury, or until the person starts resuming their everyday life and more demands are placed upon them. Sometimes, people do not recognize or admit that they are having problems. Others may not understand their problems and how the symptoms they are experiencing are impacting their daily activities.

The signs and symptoms of a concussion can be difficult to sort out. Early on, problems may be missed by the person with the concussion, family members, or doctors. People may look fine even though they are acting or feeling differently.

When to Seek Immediate Medical Attention

Cannot recognize people or places.

Are getting more and more confused, restless, or agitated.
